Definitions

  • Yet another object of the present invention is to provide a fine particle flowmeter which is reliable.
  • the guide 102 It is desirable to minimize the mass of the guide 102, and it is therefore preferably fabricated out of a sturdy lightweight material, such as aluminum, plastic, stainless steel, titanium etc. Also, it is necessary that the particles stay on the guide 102 as they move there along in order to maximize measurement accuracy side walls 122 are provided.
  • An important feature of the guide 102 resides in the relation between the pivot point 1 14 and the tangential force component of the stream of material as it contacts and travels along guide 102.
  • a strain gauge means or strain gauge 224 is mounted to one of the surfaces (in the illustrated embodiment surface 202a).
  • the preferred strain gauge is a
  • the guide means is subjected to a continuous flow of material. If the flow of the material is constant, the column 218 will deform proportionally and similarly will cause a steady-state (constant) output signal Vout to be output on lines 226 from the load cell. Any variation in flow rate will be observed as a variation in output signal Vout .
  • Vout may be digitally sampled and the information output to a control device such as a computer 400 that can be used to adjust the system as needed in order to return to the optimal flow rate.

Abstract

Un débitmètre pour déterminer le débit ou la masse d'un flux mobile de particules fines comprend un système de guidage pour guider la matière à mesurer le long d'une voie prédéterminée comportant une extrémité d'entrée et une extrémité de sortie. Un transducteur est raccordé de manière fonctionnelle à une extrémité du système de guidage; il comprend une colonne mécanique raccordée entre une cellule de mesure et l'extrémité de sortie du système de guidage. La cellule de mesure émet un signal électrique de sortie proportionnel au débit de la matière dans le système de guidage. Un système pour faire vibrer le système de guidage sert à maintenir le mouvement du flux; comme le plan des vibrations est perpendiculaire au plan de mesure, cela élimine les erreurs de mesure dues aux forces de vibration.
